The Hanalei DEM integrates bathymetry and topography in the area surrounding the town of Hanalei, Kauai. It covers the northern coast of the island of Kauai, and extends down the flanks of the volcanic edifice to the deep ocean floor. The DEM has a 1/3 arc-second (~10 meter) cell size, and is referenced to a vertical datum of mean high water. It was built in March 2011 to support NOAA's Tsunami Program.
